A blended control strategy typically increases the distance from stored grid electricity compared to a charge-depleting strategy.
Urbanization, or the move to cities, requires grid electricity, which one chapter discusses, in particular nuclear power.
If a large proportion of private vehicles were to convert to grid electricity it would increase the demand for generation and transmission, and consequent emissions.
Solar is expected to become cost-competitive with grid electricity in many regions of the country over the next 5 years.
Solar pumps are useful where grid electricity is unavailable and wind powered pumps do not provide adequate performance.
Technology advances are opening up a huge new market for solar power: the approximately 1.3 billion people around the world who don't have access to grid electricity.
There are plans to put in place underground electrical cable system for supplying grid electricity to the valley by 2011.
The price paid per kWh under a feed-in tariff exceeds the price of grid electricity.
Induction cooking using grid electricity may surpass gas efficiencies when waste heat and air comfort are quantified.
Wind turbines for grid electricity therefore need to be especially efficient at greater wind speeds.
